Noxious gasses within a vehicle interior can lead to impaired or drowsy driving, and even death in the short term, and in the longer term, may lead to a variety of illnesses of the occupants such as pulmonary issues, allergies, and the like. Noxious gasses can be produced from within the vehicle by the materials used in the vehicle, such as plastics, flame retardants, by the human or animal occupants, and can be introduced into the cabin from the exterior of the car by the ventilation system.
